Abstract
A computer-implemented method for generating a color 3D model for a dental restoration. The method receives color information, a color distribution map, and shape for a tooth. The color information is assigned to the color distribution map. The color information and the color distribution map are then combined with the shape to generate a digital color 3D model. The resulting 3D model includes volumes for different color materials for the restoration to provide for color transition zones, which can be 3D printed from the 3D model to made a corresponding restoration.

A computer-implemented method for generating a color 3D model for a dental restoration, comprising steps of executed by a processor:
- receiving color information, a color distribution map, and shape for a tooth;
- assigning the color information to the color distribution map;
- combining the assigned color information and the color distribution map with the shape;
- and
- generating a digital color 3D model based upon the assigned color information and the color distribution map combined with the shape, wherein the 3D model includes one or more segments corresponding to different color materials for the restoration and includes one or more transition zones between the color layers, each transition zone characterized by an inclined layer thickness from a first color layer and a declining layer thickness from a second color layer.
A system for generating a color 3D model for a dental restoration, comprising a processor configured to:
- receive color information, a color distribution map, and shape for a tooth;
- assign the color information to the color distribution map;
- combine the color information and the color distribution map with the shape;
- and
- generate a digital color 3D model based upon the assigned color information and the color distribution map combined with the shape, wherein the 3D model includes one or more segments corresponding to different color materials for the restoration and includes one or more transition zones between the color layers, each transition zone characterized by an inclined layer thickness from a first color layer and a declining layer thickness from a second color layer.
A computer-implemented method for generating a color 3D model for a dental restoration, comprising steps of executed by a processor:
- extracting a color distribution map from a digital representation of a tooth;
- selecting boundaries of the color distribution map in the digital representation;
- combining the boundaries of the color distribution map with the digital representation;
- matching the boundaries of the color distribution map with a digital 3D model of the tooth, wherein the matching also includes defining one or more cutting angles to generate one or more color transition zones;
- reducing an outer surface of the digital 3D model to accommodate segments for the color distribution map;
- and
- converting the outer surface of the digital 3D model to a digital 3D volumetric model.
